Research review 197
International cross-sectional survey
Short answer
In a survey of 11,910 Clue users, many reported that tracking helped them understand their cycle and prepare for menstruation. These are perceived benefits among existing app users, not proof that tracking caused improvements.
What did the researchers investigate?
Researchers surveyed 11,910 adult Clue users in May 2024. Of these, 7,898 reported concerns about their cycle or symptoms and formed the primary group for several analyses. Questions covered symptoms, coping, healthcare experiences and app use.
What did the researchers find?
Among respondents with cycle-related concerns, 96% agreed tracking helped them prepare for their period, 90% reported better understanding of their body and cycle, and 60% felt more confident speaking with healthcare professionals. Among those reporting a particular symptom of concern, 13% agreed tracking helped reduce symptoms. These are self-reported experiences.
How certain can we be?
This voluntary survey included existing Clue users and lacked a randomised comparison group. Selection effects may influence results, and causation cannot be established. The study was funded by Biowink GmbH, the company behind Clue; several authors were company employees or paid consultants.
Who do the findings apply to?
Adult Clue users from 132 countries who responded to the survey, with relatively high representation from Europe, North America and participants with higher education. It is not representative of all people who menstruate.
What might this mean in everyday life?
Knowing when a period may start and keeping a record of recurring symptoms may be useful for planning and healthcare conversations. Tracking can complement but does not replace clinical assessment and treatment.
What do we still need to know?
Independent controlled studies should test effects on actual symptom burden, quality of life, anxiety and access to appropriate care.
